AI Technical Summary

Technical Problem

The air nozzles of the existing rotary nitrogen charging device lack the lifting function, which leads to inability to contact the bottle port effectively during the nitrogen charging process, resulting in insufficient or waste of nitrogen gas, affecting the product qualification rate.

Method used

A rotating automatic lifting and charging device is designed. By automatically lifting and lowering the nitrogen filling part by using a cam mechanism during rotation, it can automatically extend into the bottle to be charged during rotation, avoid impact and meet the nitrogen filling amount requirement.

Benefits of technology

It realizes that the nitrogen filling process is automatically extended into the bottle to avoid impact with the bottle, meets the requirements for the nitrogen filling quantity of the product, improves the product qualification rate, and reduces friction through pulleys and spring structures, and improves rotational smoothness.

Abstract

The utility model discloses a rotating automatic lifting nitrogen charging device which comprises a rotating shaft, a rotating gas distribution assembly, a connecting sleeve and a rotating disc, and the rotating gas distribution assembly, the connecting sleeve and the rotating disc are coaxially installed on the rotating shaft from top to bottom and attached to each other. A cam mechanism is coaxially and fixedly arranged outside the fixed gas distribution disc, the movable gas distribution disc is fixedly connected with the rotating disc through a connecting sleeve, a plurality of nitrogen charging parts are evenly installed on the rotating disc in the circumferential direction, a gas inlet of the rotating gas distribution assembly communicates with an external nitrogen cylinder, a gas outlet of the rotating gas distribution assembly communicates with gas inlets of the nitrogen charging parts, and the nitrogen charging parts elastically penetrate through the rotating disc in the longitudinal direction. And the top is in transmission fit with the cam mechanism and is suitable for lifting up and down under the action of the cam mechanism. The nitrogen charging part can automatically ascend and descend in the rotating process, so that the nitrogen charging part can automatically extend into a bottle to be charged with nitrogen, collision with the bottle can be avoided, meanwhile, the requirement for the nitrogen charging amount of a product is met, and the qualified rate of the product is guaranteed.
